MULTIPLE-ROW PLANT-SPRAYING- MACHINE.

Application filed'J'uly 18, 1913.

To all whom it may concern:

Be it known that we, LELAND WILLIS and OLIN F. WOODWORTH, both citizensof the United States, residing in Grenloch, New Jersey, have inventedcertain Improvements in Multiple-Row Plant-Spraying Machines,

of which the following is a specification.

Our invention relates to a plant spraying device intended forsimultaneously spraying the plants of four separate rows, the inventioncomprising certain constructions and combinations of parts whereby thespraying .devices are permitted to rise when they meet withobstructions, can be readily adjusted laterally in respect to oneanother so as to accord with the varying widths at which the rows ofplants may be set apart from one another, can be raised or lowered toaccord with the height of the plants at the time the spraying operationis being performed and can be so set as to vary the direction in whichthe spray is delivered from the spraying nozzles.

In the accompanying drawings-Figure 1 is a plan view of the sprayingdevices, the bar carrying the same, the means for supporting andadjusting 'said bar, and the means for laterally adjusting the sprayingdevices on said bar; Fig. 2 is a front elevation of the spraying devicesand the supporting bar therefor; Fig. 3 is a longitudinal section on theline aa, Fig. 1; Fig. 4 is a plan view of one end of the bar whichcarries the spraying mechanism, of the devices for supporting andadjusting said bar, and

of the means for adjusting one of the sets of spraying devices on saidbar and looking it in position after adjustment; Fig. 5 is a front viewof a pair of spraying nozzles and of the means for supporting the sameso as to provide for adjustment of said spraying nozzles at differentangles of inclination in respect to the horizontal; Fig. 6 is alongitudinal section on the line bb Fig. 1, looking in the direction ofthe arrow (2 and Fig. 7 is a longitudinal section on the same line butlooking in the direction of the arrow 3 Figs. 3, 4, and 5 are on alarger scale than Figs. 1 and 2, and Figs. 6 and 7 are ona still largerscale,

The spraying devices aremounted upon a wheeled frame having rearwardlyprojecting side beams 1, upon each of which is pivotally mounted aslotted quadrant 2, to

which is rigidly secured a rearwardly proecting arm 3, the slottedquadrant being secured in any desired position of angular ad ustment inrespect to the beam 1 by means of a suitable nut and washer applied to aclamping bolt 4. carried by said side bar 1, and passing through theslot of'the quadrant.

Pivotally mounted upon the opposite arms 3 by means of projecting ears 5is a transverse bar 6 preferably of'angular cross section, and this baris also provided with another ear 7 which is connected by links 8 to alever 9, the latter being pivoted, as by a pivot bolt 10, to an angularplate 11 mounted upon the inner end of a diagonal bar 12 securedto andprojecting inwardly from the side frame 1, as shown in Figs. land 4, theaxis of the pivot bolt 10 being coincident with that of the pivot bolt13 whereb the quadrant 2 is pivoted to the side rame which carries thebar 12.

Mounted upon the upper end of the lever 9, by means of an adjustablepivotal oint 14,

'is an arm 15, provided at its upper end with a stirrup 16 for thereception of the left foot of the machine attendant, who occupies theseat 17, shown by dotted lines in Fig. 1. By means of the slottedquadrants, whereby the arms 3 are mounted upon the side frames 1 of themachine, the bar 6 can be raised and lowered to accord with the heightof theplants which are being sprayed and by means of the lever 9-thesaid bar 6 can be swung upon its pivotal bearings so as tocorrespondingly swing the spraying devices mounted. upon said bar andthus raise or lower said spraying devices to meet a temporary or localrequirement, the coinciding axes of the pivot bolts 10 and l3'permittingrise and fall of the bar 6, without disturbing in any way the mechanismfor eifecting the swinging of the bar, or changing the position of thespraying devices in respect to said bar.

pivot 10, the bar 6 will be locked in position and the spraying devicescarried by said bar may be held in an elevated or inoperative position,as for instance, when driving the machine from place to place, betweensuccessive spraying operations. The pivotal connection below the lever 9and the stirrup arm 15 permits such adjustment of the latter that thebefore mentioned swinging adjustment of the bar 6 can be effected beforethe stirrup contacts with any part of the fixed frame, ,which wouldarrest its further movement.

There are three sets of spraying devices, namely, a central set, fixedlymounted on the bar 6 in the sense of having no lateral movement thereon,and two side sets, one on the right hand side of the center of the bar 6and the other on the left hand side of the same, the machine beingdesigned to simultaneously spray the plants of four adjoining rows, andthe right and left hand sets of spraying devices being adjustablelaterally on the bar 6 so as to adapt them to the distance apart atwhich the rows may happen to be planted.

The central set of sprayingdevices has a single depending nozzle pipe'20and each of the side sets has an inner depending nozzle pipe 21 and anouter depending nozzle pipe 22. Each of the nozzle pipes 20 and 21 hasat its lower end a pair of laterally discharging nozzles 23 and 24, oneof these nozzles projecting from the pipe in a right hand direction andthe other in a left hand direction, as shown in Fig. 2. Each of theouter nozzle pipes 22 has a single nozzle 25, that of one pipeprojecting to the right and that of'the other pipe to the left, as alsoshown in Fig. 2. When the machine is in operation, therefore, thenozzles 23 and 24 of the pipe 20 will spray the inner or adjoining sidesof the innermost rows of plants, the nozzles 23- on the pipes 21 willspray the outer sides of said inner rows, the nozzles 24 of the pipes 21will spraythe inner sides of the two outer rows, and the nozzles 25 ofthe pipes 22 will spray the outer sides of said outer rows.

The nozzle pipe 20 communicates at its upper end with a pipe 26 which ispivotally mounted upon an ear 27 on the bar 6 and each of the nozzlepipes 21'is secured to and communicates with a pipe 28 which .is mountedin eye-bolts 29 on the bar 6, as shown in Fig. 7, so that it can beadjusted laterally in respect to said bar, the stems of the eyeboltspassing through the corner of the bar 6 so that said eye-bolts will besnugly conlined in the angle of said bar.

Each of the pipes 28 has a short depend ing nozzle pipe 30 having at itslower end a downwardly discharging nozzle 31, these 7 latter'nozzlesserving to spray the tops of the plants of the inner rows.

Some distance in advance of the bar 6 is a relatively short transversepipe 32 which is connected by a pipe 33 to the pumping apparatus whichsupplies the spraying liquid, and said pipe 32 communicates, through aflexible connection 34, with the pipe 26 and through similar flexibleconnections 35 with the pipes 28, as shown in;

Fig. 2.

'lhe outer end of each of the pipes 28 IS in communication through acoupling 36 and flexible connection 37 with the upper end of thecorresponding outer nozzle pipe 22 and each of said outer nozzle pipescommunicates with a short nozzle pipe 30 for instance by means of aclamp 45, as

shown in Fig. 6. Suitably mounted and guided upon the arm 40 is asliding bolt 41 which is normally moved forwardly by means of a spring42 but can be retracted when desired by reason of its connection with alever 43 pivotally mounted upon the arm 40, as' shown in Figs. 1 and 4.

In the rear edge of the upper flange of the bar 6 are formed a series ofnotches 44 located at different distances from the center of said bar,so that when either of the pipes 28 has been moved by its arm 40 to thedesired lateral position on the bar 6 it can be locked in such positionby engagement of the bolt 41 with one or other of said notches 44.

The nozzles 23 and 24 are secured to the lower ends of the nozzle pipes20 and 21 by means best shown in Figs. 3 and 5 and comprising aT-c'oupling 46 at the lower end of the pipe 20 or 21, the horizontalbranches of this T-coupling each receiving a short pipe 47 whichcommunicates, at its outer end, through an elbow 48, with the stem ofthe nozzle 23 or 24.

By turning the elbows 48 around the horizontal axes of the pipes 47,therefore, the nozzles 23 and 24 may be caused to project their sprayseither horizontally, as shown in Fig. 2, upwardly, as shown at the righthand side of Fig. 5, or downwardly as shown at the left hand side ofsaid figure, and by turning the T-coupling 46 around the vertical axisof the pipe 20 or 21 the nozzles may be caused to project their sprayseither directly sidewise or with a forward or rearward slant, as may bedesired.

The nozzles 25 may be connected to the pipes 22 in substantially thesame-manner except that in that case an elbow coupling can be usedinstead of the T-coupling 46.

can swing upwardly whenever a nozzle strikes an obstruction which exertsan upward pressure thereupon, the bar swlnging downwardly again as soonas .the obstruction has been passed.

We claim: 1; The combination, in a plant spraying machine, of a fixedframe, arms hung thereto by pivots having horizontal axes, a transversebar carrying spraying devices and.

hung to said arms by pivots having horizontal axes, a bar-swinginglever-having a pivot with horizontal axis, and connections between saidlever and the bar, the pivots of the bar-carrying arms and the pivot ofthe lever being laterally separated and independent of each other buthaving coincident axes whereby the bar can be raised or lowered withoutderanging the swinging devices therefor.

2. The combination, in a plant spraying device, of a fixed frame, armspivotally mounted thereon and having pivotally mounted at their outerends a transverse bar, spraying devices carried thereby, swingingdevices for said bar having as elements a pivoted lever, and astirrup-carrying arm having a pivotal mounting upon said lever, wherebyits angular relation thereto can be changed, as desired.

3. The combination, in a plant spraying machine, of a bar of angularcross section having eye-bolts located in the angle of the bar andhaving stems passing through the corner of said bar, and sprayingdevices carriedby a pipe which passes through said eye-bolts and isadjustable laterally therein.

4. The combination, in a plant spraying machine, of a transverse bar ofangular cross section presenting a horizontal flange with notches in therear edge thereof, a pipe carrying spraying devices and mounted in theangle of said bar so as to be laterally adjustable thereon, and an armprojecting rearwardly from said pipe and having a sliding bolt which isadapted to the notches in the rear edge of the horizontal flange of thebar.

5. The combination, in a plant spraying machine, of a pipe for supplyingspraying liquid, said pipe having a coupling at its outer end, a pipeparallel with but below said first named pipe and adjustable laterallyin respect thereto, said lower pipe ha ing depending nozzle pipes at itsopposite ends, the inner pipe being shorter than the outer pipe, aflexible connection between the couplingand the outer nozzle pipe, adown-' wardly discharging nozzle on the inner nozzle pipe, and alaterally discharging nozzle on the outer nozzle pipe.

In testimony whereof, we have signed our names to this specification, inthe presence of two subscribing witnesses.
